title: Detection of the emerging Shiga toxin-producing Escherichia coli O26:H11/H- sequence type 29 (ST29) clone in human patients and healthy cattle in Switzerland.
abstract: Shiga toxin-producing Escherichia coli O26:H11/H(-) strains showing the characteristics of the emerging human-pathogenic ST29 clone (stx2a(+) only, eae(+), plasmid gene profile hlyA(+) etpD(+)) were detected from human patients and healthy cattle, indicating a possible reservoir. Sheep also appear to shed strains related to the new pathogenic clone O26:H11/H(-) (ST29, stx1a(+) only, eae(+), plasmid gene profile hlyA(+) etpD(+)).
